feat: hide advanced fields in InspectionPanel for File and SplitText components (#12473)

* feat: hide advanced fields in InspectionPanel for File and SplitText components

- Add hidden-fields.ts to suppress advanced/deprecated fields from the
  InspectionPanel UI without removing backend functionality
- Hide silent_errors, delete_server_file_after_processing,
  ignore_unsupported_extensions, ignore_unspecified_files, pipeline,
  md_image_placeholder, md_page_break_placeholder, doc_key, and
  use_multithreading for the File (Read File) component
- Hide keep_separator for the SplitText component
- Replace deprecated use_multithreading branch with
  max(1, self.concurrency_multithreading) to preserve default behaviour

* feat: wire HIDDEN_FIELDS into InspectionPanelFields filter logic

Import HIDDEN_FIELDS map and apply it in both the edit-mode and
normal-mode field filters. Also suppress the APIRequest body field
when method is GET.

* [autofix.ci] apply automated fixes

* [autofix.ci] apply automated fixes (attempt 2/3)

* feat: hide tool_placeholder input in Prompt Template component

Set show=False on the tool_placeholder input so it does not appear
in the UI while retaining tool mode functionality.

* [autofix.ci] apply automated fixes

* feat: hide include_metadata field for DynamicCreateData in InspectionPanel

* [autofix.ci] apply automated fixes

* fix: add trailing newline to component_index.json

The build_component_index.py script was generating component_index.json
without a trailing newline, causing CI failures when autofix.ci tried to
add the missing newline. This fix ensures the generated JSON file always
ends with a newline character, following POSIX text file standards.

Fixes the 'No newline at end of file' error in the update-component-index
workflow job.
